CHARGE MIXING AND ATOMIZING DEVICE OF INTERNAL COMBUSTION ENGINES Filed May 19. 1928 Patented Feb. 25, 1930 PATENT OFFICE WALTER HULLEY, OF BLACKPOOL, ENGLAND CHARGE MIXING AND ATOMIZING DEVICE INTERNAL-COMBUSTION ENGINES Application filed. May 19, 1928, Serial No. 279,146, and in Great Britain May 9, 1927.

This invention relates to improvements in charge mixing and atomizing devices for internal combustion engines.

According to the invention, two or more screws or propellers are mounted in the induction pipe between the carburettor and the engine adjacent propellers being adapted to be rotated in opposite directions by the suction in the induction pipe. i0 7 The invention will be described with reference to the accompanying drawings I Fig. 1. Front View of the atomizing device having two screws or propellers.

Fig. 5. Plan view of the atomizing device having three screws or propellers.

' Fig. 6. Plan view of atomizingdevicehaving two screws or propellers both mounted on the same side of the flange or bracket.

Fig.7. Plan view of atomizing devicewith three screws or propellers both mounted on the same side.

As shown in Figs. 1 to 3 two screws or propellers A are mounted to rotate on loose sleeves Z) on a stud or pin B carried in a bar 0 extending diametrically across a circular or approximately'circular aperture in a flange or bracket 0. The flange or bracket C is of approximately oval'shape and is adapted to be bolted between similarly shaped brackets on the induction pipe. The propellers A are arranged to rotate in opposite directions and extend one on either side of the flange or bracket C so that they will project respectively into the induction pipe and the intake pipe. The propellers A are co-axial' with the pipes at the points where they project thereinto. The pin or stud B may be provided at one end with a head C and at the other be screwed at the end to receive a nut c to hold the screws or propellers A in position or it may be riveted over at the ends.

Asshown in Fig. 5 threepropellers A may direction to the outer propellers.

be employed. two at one side of the flange or bracket O and one at the other side, the central propeller rotating in the opposite Or as shown in Fig. 6, two propellers A. may be employed both mounted on the same side of the flange or bracket C.

I claim: A charge mixing and atomizing device for internal combustion engines comprising a supporting plate adapted to be connected between the induction and intake pipes and having an opening therein to establish communication between'the pipes, said plate including a supporting member located axially of the pipes, a bolt passing through said supporting member axially of the pipes, bearing sleeves of uniform diameter throughout surrounding said bolt and held rigidly secured to the supporting member by the bolt, and a plurality of propeller devices loosely mounted on said sleeves, each propellerdevice including a hub having three blades extending radially therefrom, said bladesbeing disposed at an angle of approximately 45 to a plane radial to the axis of rotation and being substantially of the same width throughout from the hub to the ends thereof whereby a more thorough churning and beating action on the passing vapor charge is obtained, the total length of the hubs when mounted on the sleeves being less than the total length of the sleeves whereby a rigid support is provided on which the propeller blades are free to rotate.

In witness whereof I alfix my signature.

WALTER HULLEY.
